EUROCONTROL provides support to the ATM community in planning and reporting their progress on implementing the ATM Master Plan (level 3).
Every year, we take stock of where each one of the ECAC States (and Comprehensive Agreement States) is in terms of implementing the ATM Master Plan (level 3). The results of this reporting exercise are compiled in a set of Local Single Sky ImPlementation (LSSIP) documents. The LSSIP documents then feed into the annual European ATM Master Plan Level 3 Progress Report.
